Application fi'led June 22,1925. .Serial No.- 38,662. i

This invention line fasteners, and more particularly to 'a clampingdevice for use in holding clothes lines, tent cords, and the like.

One object ofthis invention is to provide a device of this nature'inwhich the line is held by a rotary cam wheel in cooperation with a bodymember in which the cam wheel is journaled.

A further object is to provide a device of this nature which will besimple in construction, inexpensive to manufacture, easy to manipulate,and very efiieient and durable in use.

With these and other objects in view, there has been illustrated on theaccompanying drawings, one form in. which the invention may beconvenientlyembodied in practice.

Fig. 5 is a view of the line clamp as it" appears when assembled upon atent cord.

Referring now to the drawings in which like reference numeralsdenotecorresponding parts throughout the several views, the numeral 10indicates a body member, gen erally semi-cylindrical in cross-section,and having a longitudinal passage 11 adapted to receive the knotted end12 of a cord 18.

The body member 10 is provided with a pair of side wings 14 and 15 whichare arranged parallel toeach other and which form bearings for a rotarycam wheel 16. As mostclearly shown in Figs. 2and 3, the cam wheel 16 isrigidly mounted upon a pivot pin 17 which is adapted to rotate insuitable apertures in the side Wings 14 and 15.

The cam wheel 16is reduced in diameter at its center to form a curvedannular neck section 18 which is adaptedto cooperate with a circulargroove 19 in the body member 10 to form a channel for the free end ofthe cord 13 when said cord is held centrally and parallel to the sidewings 14; and 15.

In orderto lock said free end in any adjusted position,.the rotary camwheel is provided at its ends with a pair of spiral relates toimprovements in' Fig. 1 representsa side view of the line grooves 20*and21, said grooves being oppositely -p1tched By means m this construction,when the line clamp is twisted so as to bring the cord either to theright or position, the cord will be "engaged by one of said left of itscentral grooves and held tightly against thejbody member 10.

Forthe purpose the free end 23 of the cold, the side wing 14 is providedon one edge with aninclinedslot 22- through which is passed theextremity of the free end 23 which projects beyond the cam wheel 16.

V The use of the device as a clothes line clamp isclearly illustrated inFig. 4 where the intermediate portion 23 of the cord 13 is shown passingaround a pair of pulleys 24 and 25, said pulleys being connected to apair of posts 25 and 25 Fig. 5 illustrates the use of the device for.holding a tent cord.

In this figure the intermediate portion 23* of the cord is passed arounda notched stake 26 which is driven into the ground adjacent the'edge ofthe tent 27.

he]. and into one of the side grooves of said hen theline fastener lsrecam wheel;

of more firmly locking leased, the resiliency of the cord will causesaid cord to be clamped by thecam wheel 16 tightly against the bodymember 10.

lVhile there has been disclosed in this specification one form in whichthe invention may be embodied, it is to be understood that this form isshown for the purpose of illustration only, and that the invention isnot to be limited to the specific disclosure but may be modified andembodied in various other forms without departing from its spirit. themodifications and embodiments coming within the scope of the followingclaims.

Having thus fully described the inven- I tion, what is claimed as new,and for which it is desired to secure Letters Patent, 1s:

1. In a clothes line elamp,a body member, I

a pair of side members depending from said ody member, a rotarycam wheeljournaled in said side members, said body member having a longitudinal.passage to receive the In' short, the invention includes all knotted endof a cord, one of said side mem- 77 bars having an inclined slot toreceive the other end of said cord around said cam Wheel.

2. In a line clamp, a body member adapted to hold one end of a cord, arotary cam Wheel journaled in said body member, said cam wheel having aspiral groove in one side after it has passed adapted to engage and holdthe other end of said cord when said clamp is twisted, said body memberhaving a depending Wing member adjacent said cam wheel, said wing memberhaving an inclined slot to also receive said other end and serve as anadditional lock therefor.

In testimony whereof, I have affixed my signature to this specification.

THOMAS P. DUNNE.
